Chapter 13 Ear Anatomy
Across
- 4. sensory organs of balance, provides information about the body's position to maintain equilibrium
- 6. directs sound waves into the external auditory canal
- 10. portion of the temporal bone of the skill posterior and inferior to each auditory canal
- 11. conveys information about sound, including volume and frequency, from the cochlea to the brain
- 12. conveys information about the position and balance from the semicircular canals and vestibule to the brain
- 15. bones of the middle ear that carry sound vibrations
- 16. bony spaces within the temporal bone of the skull made up of three distinctive parts, the cochlea, semicircular canals, and the vestibule to facilitate equilibrium and balance
Down
- 1. semitransparent membrane that separates the external auditory canal and the middle ear cavity
- 2. paired cranial nerves responsible for hearing and balance
- 3. consists of labryinth and connectors of the vestibular and the cochlear nerves
- 5. coiled portion of the inner ear containing the sensory organ for hearing
- 7. short tube that ends at the tympanic membrane
- 8. consists of the auricle and external auditory canal
- 9. consists of the tympanic membrane and the tympanic cavity containing the ossicles
- 13. organ of hearing
- 14. passage between the middle ear and the pharynx, equalizes air pressure on both sides of the tympanic membrane
